Subject: [PATCH] media: venus: flush all buffers in output plane streamoff
Date: Mon,  8 Jan 2024 12:03:34 +0530
Message-Id: <1704695615-1036-1-git-send-email-quic_dikshita@quicinc.com>
Precedence: bulk

For scenarios, when source change is followed by VIDIOC_STREAMOFF
on output plane, driver should discard any queued OUTPUT
buffers, which are not decoded or dequeued.
Flush with HFI_FLUSH_INPUT does not have any actual impact.
So, fix it, by invoking HFI_FLUSH_ALL, which will flush all
queued buffers.
